JDBC Driver for Oracle

Introduction to JDBC Driver for Oracle

Firstly, the full form of JDBC is known to be Java Database Connectivity which is normally a Java API implemented for executing and also connecting query with the server database. This JDBC driver is reflected to be a fragment of Java SE which is Java Standard Edition. JDBC’s API creates an implementation of JDBC drivers so that its connection can be established with the database. Here, JDBC API may be applied for accessing the database tabular records warehoused in any of the relational databases. With the help of JDBC API or driver user has the capability of saving, deleting, updating, and further fetching the data records from the database. It is also measured as Open Database Connectivity which is ODBC delivered by Microsoft. Let us Discuss the JDBC Driver for Oracle.

How does JDBC Driver Work for Oracle?

Let us view the following steps for connecting java applications with the Oracle database server knowing certain information regarding the Oracle database where for instance we will implement the database named as Oracle 10g:

• Driver class: For the Oracle database, the driver class is oracle.jdbc.driver.OracleDriver.
• Connection URL: For the Oracle 10g database, the connection URL where jdbc denotes the API, thin indicates the driver, oracle provides the database, also implement ID address, localhost refers the name of server on which the oracle is performing, XE denotes the Oracle Service number and 1521 refers the port number is jdbc:oracle:thin@localhost:1521:xe. To receive the info data 1521 we can refer the file known as tnsnames.ora.
• Username: The username by default for the Oracle database is defined as system.
• Password: It is the required specific password provided by the user for the Oracle database at the time of deployment.

Advantages and Disadvantages

We have listed some of the advantages of the JDBC driver for Oracle as follows:

• JDBC driver for Oracle by Progress DataDirect delivers a safe and sound, high-performing and consistent connectivity solution implemented for JDBC applications for accessing Oracle database data.
• This JDBC driver may be simply applied with SQL diagonally on both 64-bit and 32-bit platforms.
• Provides actual-time analytics, reportage, and business intelligence proficiencies along with the special tools like SAS, Yellowfin, Sisense, SAP, Cognos, Denode, Tibco, OBIEE, Tableau, Jaspersoft, and so on.
• By means of the tested JDBC driver, one can enhance the scalability and performance of the applications.
• Have support for all versions of Oracle 9i, 8i, 11g, 10g, 18c, 12c in one driver.
• Continuously updated thus removing the risks and ensuring flexibility.
• Both synchronous and asynchronous handling can be supported.

In the same way, few disadvantages of this JDBC driver for Oracle are mentioned as follows:

• This can be very sensitive and important to deploy correct drivers for each type of server database so that it functions well. It may be time-consuming and so challenging part.
• It may not permit one sequence for the update or insertion of many tables.

Usage of JDBC Driver for Oracle

The JDBC basically is an application of the Java programming language which orders how databases connect with each other. The connectivity from the DBMS (Database management systems) to an inclusive range of SQL databases is skilled by means of a standardized application programming interface i.e. API. By installing database drivers fastened with JDBC technology, it becomes possible to establish a connection with any database and also in a heterogeneous environment so that the tables, flat files, tabular records and so on can be accessed.

With the use of JDBC, many Java programmers have the capability to appeal connections to a database, conduct query commands to the database by means of SQL statements and instantly delivery of outcomes for innovative processing.

Some of the features are provided below for JDBC driver:

• SQL up levelling with full support for ANSI SQL that manages to query SQL commands which can be executed over many databases.
• Encryption service SSL 3.0 and TSL 1.0, 1.1, 1.2 Compliant to address any security vulnerability issues.
• Tuning the performance with optimization of data buffering.
• TSANet support channel with Multi-vendor to support 24/7 partner and contact to expertise within the engineering teams.
• For any new versions day 1 support
• Type 5 JDBC driver with high-performing
• Export and codeless bulk load

Examples of JDBC Driver for Oracle

Let us discuss some of the examples to illustrate JDBC driver for Oracle as follows:

Oracle offers four kinds of JDBC driver mentioned as follows:

• Thin Driver: This is a 100% Java driver implemented for client-side applications but there is no need for Oracle installation, especially with applets. The thin driver is the thin kind. Using this, for connecting user having a distinct user name and password to a database server with SID orcl (System identifier) through port 1521 of the host having hostname.
• OCI Driver: It has client-side implementation with an Oracle client installation. This driver has type oci. For connecting the user with username having the password to a database with system identifier (SID) orcl using port 1521 of the host with hostname and by means of OCI driver. Note that if the Oracle server and JDBC client are executing on the identical machine, then as an alternative of a network connection the OCI driver uses IPC i.e. InterProcess Communication for connecting to the database since an IPC connection is quicker than a network one.
• Server-Side Thin Driver: This driver performs similar to the client-side thin driver on the basis of functionality but it’s actually for code that executes within an Oracle server and requires to access a server working remotely comprising middle-tier scenarios. The driver type is thin.
• Server-Side Internal Driver: This driver is for the code that executes within the target server which is privileged in the Oracle server which it needs to be accessed. The driver type is kprb that essentially performs in a default session.

Conclusion

We have come to know that the JDBC driver for Oracle is a standard of Java Database Connectivity that offers a mechanism to associate to databases for Java programs. A JDBC driver is a must require to access the server databases by means of JDBC. Also, JDBC drivers are delivered as free downloads by the database vendors.
